Hi all, son of Stubby47 here. Just thought I would drop in to add some context behind the initial prompt of this thread.
Now I cannot claim to be a huge model rail enthusiast, I've never had the creative expertise or technical knowhow to even know where to begin; instead finding a rather niche interest in worldbuilding, map making, and just generally being a nerd for most things historical. And it was with one of my latest sessions of procrastination that I learned about the mythical land of Lyonesse which supposedly lies of the coast of Cornwall between Lands End and the Isles of Scilly.
I decided that I wanted to create a map of such a place, and taking inspiration from another map online, have been creating this (I've hit upload but I've no idea where that picture is going to appear).
My main line of questioning to father about this was as follows: Had the island followed in the footsteps of the West Cornwall Railway and had been 7ft wide (Perhaps also designed by Brunel or the like), following the WCR being bought out by the Great Western Railway, would it have become standard gauge, and if not, what the rolling stock look like if it still existed today.
To my understanding, the line between Penzance and Truro was broad gauge whilst Truro to Plymouth was Standard, meaning that passengers would have to change trains to continue their journey. Given that anyone traveling from my town of Carncreag or Gwermouth would have had to exchange at Kerlew regardless of the gauge, does this mean that the gauge would have remained untouched despite the GWR potentially taking over.
I know there are many factors to play here; would there have even been a standard railway on the island in the first place, would it all have been narrow gauge or axed by Beeching in the 60s; all that and more, but I'd be curious to hear anyones thoughts on the subject.
Finally, please understand that I am not an expert on railways, and so anything I have said here might be incredibly wrong or narrowminded, so be gentle with me.
Thank you!
